sical name {^Ixiaipa in Aristotle, umbra in Ovid, 



Distinguished by Artedi" under a limitation so 

 wide as to correspond very nearly to the Sciajnoid family 

 of our times, this genus now includes only those spe- 

 cies Avhich agree Avith the characters, chiefly negative 

 ones, ^vhich are given above and are the expression of 

 tlie most typical generic form in the family. About 

 .50 known species range themselves under these cha- 

 racters. The genus is spi'ead over the Old World and 

 the New, tlie Atlantic Ocean and the Pacific. Its clas- 



CoLUMELLA and, at a later time, 1.554, in Salvianus; 

 ombrina among the Romans of the present day) means 

 'shadow-fish''', but is difficult to explain, as the accounts 

 of this genus given by the ancients are very meagre. 

 In India, where these fishes are ;ui important article of 

 food and where, according to Day", their air-bladder 

 is made into isinglass and exported to China, they 

 are called Bola in Bengali.
